聚硅硫酸铝絮凝剂的制备及应用

Preparation and application for polymeric basic aluminum silicate-sulphate flocculent

以硅酸钠和硫酸铝为原料,采用复合共聚法制备聚硅硫酸铝絮凝剂,考察了该絮凝剂应用污水的处理效果并和聚合硫酸铝作比较,结果表明:聚硅硫酸铝对牛奶污水有很好的处理效果,残留铝量低,优于高分子絮凝剂聚合硫酸铝。

PASS flocculent was prepared by composite-copolymerization with Al2（SO4）3 and Na2SiO3 in this paper,the experiment for application show that PASS is very efficient for the water treatment,and the flocculent effect of PASS is superior to that of PAS.
